Sequence-of-Returns Risk: Why the First Five Retirement Years Matter Most

Sequence-of-returns risk is the danger that poor investment returns early in retirement, while you are also withdrawing money, permanently damage your savings even if your long-term average return is fine. Because you are selling assets at low prices to pay bills, the portfolio has fewer shares left to recover. The order of your returns, not just the average, decides whether your money lasts.

Picture a well in your backyard that you draw water from every day. Over thirty years the rain evens out to the same steady average. But the order the rain arrives in is not guaranteed. If a long drought hits in the first few years, right when you have started drawing water hard, the water table drops fast. There is less water left underground to catch the rain when it finally returns, and the well can run dry decades before the “average rainfall” would have predicted. If instead the drought comes late, after years of good rain have kept the water table high, the well shrugs it off.

Same total rainfall. Same average. Completely different outcome, decided entirely by timing. That is sequence-of-returns risk, and it is the single most underappreciated danger in retirement. During your working years it barely matters, because you are adding water, not drawing it. The moment you retire and start living off the well, the order of the weather becomes one of the most important things in your financial life, and it is the one thing you do not control.

This guide explains exactly how it works, shows it with a clean side-by-side example, and lays out the honest menu of ways to defend against it. By the end you will understand why the five years on either side of your retirement date carry more weight than any other stretch of your investing life.

What is sequence-of-returns risk?

Sequence-of-returns risk is the risk that the order in which your investment returns occur damages your retirement savings, even when the average return over time is perfectly acceptable. The idea was introduced to the financial planning profession by William Bengen, whose 1994 research on safe withdrawal rates in the Journal of Financial Planning showed that timing, not just average performance, governs how long a portfolio lasts. When you are withdrawing money, a run of bad early returns forces you to sell more shares at depressed prices to raise the same amount of cash. Those sold shares are gone and cannot participate in the eventual recovery, so the portfolio starts the rebound with a smaller base and may never catch back up.

The key mental shift is this: the average return of your portfolio and the safe income it can produce are two different things. Two retirees can experience the identical average annual return over the same number of years and end up in opposite situations, one comfortable and one broke, purely because the good and bad years arrived in a different order. The next section proves it with numbers.

Why does the order of returns matter if the average is the same?

The order matters because withdrawals and losses compound against each other, so a dollar lost early is far more expensive than a dollar lost late. When your portfolio falls in an early year and you also pull out cash for living expenses, you deplete the account from two directions at once. The shares you sell to fund that year’s spending are locked in at a low price, and they are no longer there to grow when the market rebounds. A loss late in retirement lands on a portfolio that has already had years to compound, so it does far less lasting damage.

This is why a simple average is misleading once you are spending down. A portfolio that averages 7 percent by earning it steadily behaves nothing like a portfolio that averages 7 percent by crashing early and soaring later, if you are withdrawing the whole time. During the accumulation years, when you are adding money rather than taking it out, the effect essentially reverses and early losses can even help you by letting you buy in cheap. Everything flips at the moment you start living off the money.

The two-retiree example

The cleanest way to see sequence-of-returns risk is to compare two retirees who get the exact same set of annual returns in reverse order. The table below is illustrative and uses simplified assumptions, stated plainly so you can follow the math, not a projection of any real product or account.

Look at what happened. Both retirees earned the identical six returns and took the identical 25,000 dollars a year. Retiree B, who happened to get the good years first, ends the stretch with about 402,000 dollars. Retiree A, who got the bad years first, ends with about 335,000 dollars, roughly 67,000 dollars behind, despite doing nothing different and earning the same average. Stretch this over a full 25 or 30 year retirement with real market swings, and that early gap is often the difference between money that lasts and money that runs out.

The lesson is not “avoid the market.” It is that the same portfolio can succeed or fail based on something you cannot schedule, so a retirement plan has to account for the possibility that your bad years land first.

Does sequence risk matter before you retire?

No, sequence-of-returns risk barely matters while you are still saving, and understanding why reveals the whole mechanism. During your working years you are contributing money, not withdrawing it, so an early market crash is actually an opportunity: your regular contributions buy shares at lower prices, and those cheap shares grow when the market recovers. Only the average return over your whole accumulation period really drives your ending balance, and the order matters very little.

Everything inverts the day you flip from adding to withdrawing. Now a crash forces you to sell shares to fund your lifestyle instead of buying them. This is why the risk is concentrated so tightly around the retirement date itself. Someone 20 years from retirement can watch a brutal down year with relative calm. Someone who retired eleven months ago is in the most dangerous window of their financial life, and most people have no idea that the window even exists.

What is the fragile decade?

The fragile decade is the roughly ten-year window, about five years before retirement and five years after, when your portfolio is most vulnerable to sequence-of-returns risk. It is the period when your account balance is near its lifetime peak and you are on the verge of, or just beginning, to draw it down. A severe market decline during this stretch does damage that later returns struggle to repair, because you no longer have decades of contributions and compounding ahead of you to recover.

Think of it as the narrow, exposed part of a mountain trail. The same storm that is a minor inconvenience at the base of the mountain, where you have shelter and options, can be genuinely dangerous on the exposed ridge with a long drop on either side. The fragile decade is your exposed ridge. The practical takeaway is that risk management should tighten as you approach it and loosen again once you are safely past it with a plan that has held. The defenses below are how you cross the ridge without being at the mercy of the weather.

How do you protect against sequence-of-returns risk?

You protect against sequence risk by making sure you do not have to sell investments at a loss during the fragile decade. Every real defense is a version of that one idea. Here is the honest menu, with the trade-off attached to each, because none of them is free.

Notice the through-line. Cash buffers, bond tents, flexible spending, delayed Social Security, and guaranteed income are all ways of ensuring the market cannot force your hand in the exact years you are most fragile. Strong plans usually combine two or three of them. If your essential expenses are not yet fully covered by reliable income, our guide to finding and closing your retirement income gap is the natural companion to this page.

Where do guaranteed-income annuities fit?

Guaranteed-income annuities fit sequence-risk planning by covering your non-negotiable expenses with market-proof income, which removes the pressure to sell investments during a downturn. When your essential bills are paid by a source that keeps arriving no matter what the market does, an early crash becomes something your portfolio can wait out rather than something that forces a fire sale. In effect, the annuity absorbs the sequence risk on the slice of your money dedicated to income, and your remaining investments are freed to ride out volatility on their own schedule.

A couple of product types are commonly used this way:

The trade-offs deserve equal weight, because this is a tool, not a cure:

• Liquidity. Money placed in income or fixed index annuities is typically subject to a surrender period, so it is not fully accessible for years. It should be money you do not need on hand.
• Growth ceiling. The protection against loss on a fixed index annuity comes at the cost of capped upside. In a roaring bull market it will trail a fully invested stock portfolio. That is the deliberate trade: you give up some of the top to protect the bottom.
• It is not FDIC insured. An annuity’s guarantees rest on the claims-paying ability of the issuing insurance company, not a bank or the federal government. Check the carrier’s independent financial-strength rating, such as AM Best, before you commit.
• Complexity. Caps, participation rates, and riders vary widely between carriers and change over time, so the details matter and should be read closely rather than taken on a headline.

Used for the right slice of your money, guaranteed income is one of the most direct ways to neutralize sequence-of-returns risk. Used for money you might need next year, it is the wrong tool. The annuities hub lays out the full product family so you can see where each one fits.

Moving forward

Go back to the well one last time. You cannot control when the drought comes. What you can control is how you draw water: keeping a reserve for dry spells, not pumping the well hard the moment the sky turns gray, and making sure at least part of your water supply does not depend on this season’s rain at all. That is the entire strategy for sequence-of-returns risk in one picture.

The fragile decade is coming for everyone who retires, and the retirees who sail through it are almost never the ones who guessed the market right. They are the ones who arranged their income so a bad early market could not force their hand. The right mix of a cash buffer, flexible spending, a smart Social Security decision, and guaranteed income depends entirely on your own numbers and your own timeline. The worst way to sort that out is guessing from a blog post. AnnuaLife matches you with a Certified Annuity Advisor who will run your actual plan against a bad-early-returns scenario and show you every defense, with the trade-offs, before you commit anything. That is how you cross the ridge on purpose.
